On some machines you may encounter the annoying Dead Space invisible wall issue. This issue usually appears in the room in which you first get the plasma cutter. After the cutscene completes you cannot pass through the door. You can see exactly what this looks like in the video below:

The solution to this issue for most people is the same on that solves the Dead Space mouse lag issue:

Turn on VSync in your control panel. Load your NVIDIA Control Panel and under manage 3D settings change your Vertical sync option to “On”. You can do this either in the Global Settings (force on for all programs) or in the Program Settings under the Dead Space entry.

Turn off VSync in game. Start Dead Space, go to to options > visuals and toggle VSync off. If you can’t start the game to disable VSync see this post for some potential solutions to startup crashes.

If you’ve followed the above steps and are still experiencing the Dead Space invisible wall issue, please post in the comments below. To increase your chances of a solution being found include as much detail as possible (which version of the game you’re running, what operating system you have, what video card you have and steps to reproduce the issue). Screenshots are also very useful!
